Whakaahuatanga Poto:
Ko te 660A e pā ana ki tētahi āhua motuhake o te koranu A286 (UNS S66286), he maitai kore waikura kaha-teitei, pāmahana-teitei, ā, ātete-waikura.
Pae Kowiri tira 660A:
Ko te ASTM A453 Grade 660 he maitai kore waikura austenitic whakapakeketanga e whakamahia whānuitia ana mō ngā rauemi whakamau me te whakapiri i te pāmahana teitei. Ko te āhua 660A o te maitai kore waikura A286 he mea whakamahana ki te wai, e whakarato ana i te taurite o te kaha teitei, te kaha hanga pai, me te ātete waikura pai rawa atu. Nā tēnei ka pai mō ngā tono uaua i roto i ngā rāngai rererangi, motuka, me ngā ahumahi e tika ana kia mahi pono ngā rauemi i raro i ngā āhuatanga ahotea teitei me te pāmahana teitei. He ātete tino pai ki te waikura me te waikura i roto i ngā taiao pāmahana teitei. He ātete pai ki ngā momo taiao waikura, tae atu ki te wai moana, ngā waikawa ngawari, me ngā kawakore.
